Yes the endocrine system does contain organs. The endocrine system as you probably know is responsible for the synthesis and secretion of hormones. The following are endocrine glands and an example or two of hormones they produce (most of these glands produce multiple hormones): hypothalamus (produces dopamine, antidiuretic hormone), pituitary gland (produces growth hormone), thyroid (thyroxin), parathyroid (parathyroid hormone), adrenal glands (produces adrenaline), heart (produces atrial-natriuretic peptide), stomach (produces gastrin), liver (angiotensenogen), pancreas (insulin, glucagon,) kidney (erythropoietin), skin (vitamin D3), adipose tissue/fat (leptin, estrogens), testes (testosterone), ovary follicle (develops egg; produces estrogens), corpus luteum ("scar" in ovary resulting post ovulation; produces progesterone, estrogens), placenta (progesterone).
